Which classification system is used for gastric?
Since its establishment in 1965, the Laurén classification of gastric cancer has been the most commonly used and the most studied classification for gastric adenocarcinoma among all of the classification systems.
WHO histological classification of gastric Tumours?
The 2010 WHO classification recognizes four major histologic patterns of gastric cancers: tubular, papillary, mucinous and poorly cohesive (including signet ring cell carcinoma), plus uncommon histologic variants (24).
What is the Lauren classification?
The Lauren classification is based on how the gastric tissue looks and behaves when examined under a microscope. This is the system most often used to describe how adenocarcinoma tumours, the most common type of stomach cancer, look and behave.
What are the types of gastric adenocarcinoma?
There are 2 main types of stomach adenocarcinomas: The intestinal type tends to have a slightly better prognosis (outlook). The cancer cells are more likely to have certain gene changes that might allow for treatment with targeted drug therapy. The diffuse type tends to grow spread more quickly.
What process distinguishes malignant tumors from benign tumors?
Some tumors are benign, which means they form in only one spot without spreading to surrounding tissue. Malignant tumors are cancerous and can spread to nearby tissue.
What process distinguishes a benign from a malignant tumor?
How is moderately differentiated adenocarcinoma treated?
There are three main treatments for adenocarcinoma:
- Surgery. Usually the first line of treatment for adenocarcinoma, surgery is done to remove cancer and some of the surrounding tissue.
- Chemotherapy. This treatment involves using drugs to kill cancer cells.
- Radiation therapy.
What is Borrmann’s classification for CA stomach?
Borrmann’s classification for ca stomach. Borrmann’s classification is for advanced gastric tumors. It is useful to distinguish between advanced and early gastric tumors because in advanced tumors neo adjuvant therapy improves over all survival.
What is Bormann’s classification?
Bormann’s classification Type I lesions—Pedunculated and exophytic. Type II lesions—Ulcer craters confined to mucosa and submucosa. Type III lesions extend into the muscularis.
What is the gross appearance of advanced gastric carcinoma?
The gross appearance of advanced gastric carcinomas can be exophytic, ulcerated, infiltrative or combined. Based on Borrmann’s classification, the gross appearance of advanced gastric carcinomas can be divided into type I for polypoid growth, type II for fungating growth, type III for ulcerating growth,…
What is the prognosis of early gastric carcinoma?
Some early gastric carcinoma can be multifocal, often indicative of a worse prognosis. Grossly, early gastric carcinoma is divided into Type I for the tumor with protruding growth, Type II with superficial growth, Type III with excavating growth, and Type IV for infiltrating growth with lateral spreading.
